Thyristor modules MT3, MT4, MT5

Power SRC dual thyristor modules MT AS ENERGI^TM are a monolithic design with two semiconductor thyristors (type thyristor-thyristor), operate in DC and AC circuits with loads from 115A up to 1250A and reverse pulse voltages up to 6500V.

Connection diagram of modules: MT3 – half-bridge; MT4 – common cathode circuit; MT5 – common anode circuit.

High energy-thermocyclic resistance and reliable operation of low-frequency thyristor modules of MT when switching high currents is achieved due to their design features and stable parameters galvanic separation:

• the dielectric strength of the insulation between the potential-free base and the leads reaches the mark 3600V under normal climatic conditions and 1500V at high humidity;
• housing is made of non-combustible thermopolymer;
• the dielectric strength of the insulation between the main and control leads reaches the mark of 2500V under normal climatic conditions and 1500V at high humidity;
• the insulation resistance between the potential-free base and the outputs under normal climatic conditions is at least 50МОм and no less than 5МОм at high humidity;
• insulation resistance between main and control leads under normal climatic conditions is at least 1000МОм and no less than 100МОм at high humidity;

Thyristor modules MT3, MT4, MT5 have a clamping design, mounting with screws through the through mounting holes in the housing. The wires are fastened with nickel-plated terminals, under which the test points for measuring the pulse direct voltage are placed. Main leads are on the top of the case and are numbered 1, 2, 3. Control leads are marked on the diagram as G1, G2. Additional cathodes are marked on the diagram as K1, K2.

When mounting thyristor modules, special attention should be paid to the tightness of the mating surfaces – concavity more than 0.03 mm is not allowed.

To mount additional cooling (radiators or coolers are used), mounting holes are provided in the housing of the thyristor potential-free modules. A special thermally conductive substrate lubricated with thermal paste must be used between the module and the cooling element.

Thyristor modules MT3, MT4, MT5 are used in various power installations - power and control units, power regulators, AC regulators, inverters, motor starters and controls, temperature controllers of blast furnaces or chemical processes, welding equipment, etc.

Our modules are offered in several dual and single device topologies for almost all phase control or rectifier applications.

Our company provides a quality guarantee for thyristor / diode modules of 2 years from the date of purchase. When supplying thyristor / diode modules, if necessary, we provide technical passport and certificate of conformity.

The final price for thyristor / diode modules depends on the class, quantity, delivery terms, manufacturer, country of origin and form of payment.
